Abstract: PURPOSE: A virtual machine-using file system management device and a method thereof easily and timely analyze an error taking place in a file system due to a certain activity of the system or an object by setting a certain file in the system or a certain object as a monitoring point. CONSTITUTION: A virtual machine (VM) (120) includes an operating system with a kernel module (122) for analyzing a file system (123). A control unit (110) controls the VM, sets a certain point of the kernel chosen by a user as a monitoring point, notifies a display unit about the setting of the monitoring point, and requests the VM to generate a snap shot for the monitoring point. Upon the request by the control unit, the VM generates a snap shot for the monitoring point. The control unit sets the monitoring points only on those files corresponding to a certain path of the file system, certain i-nodes, or certain blocks as a debugging target. [Reference numerals] (110) Control unit; (120) Virtual machine; (121) Operating system; (122) Kernel module; (123) File system; (AA) Snap shot generation; (BB) Snap shot 1; (CC) Snap shot 2; (DD) Snap shot 3; (EE) Monitoring point setting; (FF) Monitoring point reporting; (GG) Snap shot generation request; (HH) Snap shot analysis; (II) Snap shot n
